Why is there no signal when the mobile phone leaves the province?

If there is no signal on your phone or an emergency call prompt is displayed on the screen, it is recommended:

2.If it is a dual-SIM phone, please check whether the SIM card is activated: Settings - SIM Manager - SIM1 SIM2 - Click the SIM card icon - slide to turn on (the operation mode may be slightly different for different models of mobile phones).

3.If there is still no signal, it is recommended to turn off the SIM card and remove it, wipe the SIM card chip with an eraser, and then reinstall it.

4.If it doesn't work, try to change to another location to rule out whether it is caused by poor signal coverage in your location.

5.Try to change the network mode to 3G or 2G (do not select the auto-connect mode). Note: Some machines do not support changing the network mode.

6.Try to change another SIM card.

7.Update your phone's system version: Settings - About Phone (About Device) - Manual Update Automatic Update (Software Update System Update - Update). Note: Please back up the data (contacts, messages, **, etc.) in your device before upgrading.

If there is still no signal or emergency call is displayed after the above operations, please bring the purchase invoice, warranty card and machine to the nearest service center for inspection.

The card you bought may be a local card, you can't roam, so it's not good to go out of the province, you just need to call the 10086 manual desk, turn the form to turn it into a roaming can I hope it can help you.

Trouble, thanks!

You have to go to the mobile hall to open a business that goes out of the province to roaming the roaming business, and there is no charge for opening this business with many cards, depending on what card it is.

1. Cause of failure: 1. Network problem or network cannot be covered. When the network coverage is not good, it is generally located in mountainous areas, basements, elevators, and when there is shielding or signal interference, there will be no signal or very weak.

In the process of debugging, optimization and maintenance, the network may also cause signal instability, and the general network will return to normal, and the mobile phone signal will return to normal. 2. Problems with the mobile phone itself. There may be a problem with your phone's receiver.

You need to go to the repair point to have a look. Of course, the factor of SIM card corruption cannot be ruled out. 2. Solution 1: Check whether the mobile phone card slot or the SIM card containing the car is damaged

You can insert other mobile phone cards to try, and then put the SIM card of the mobile phone itself on other mobile phones to see if there is a signal, if the card slot is damaged, it is recommended to replace the card slot, if the SIM card is damaged, please go to the business hall to replace the SIM card. 2. There is no signal on the mobile phone caused by network delay: you can turn on the airplane mode of the mobile phone, turn it off after five seconds, or restart the mobile phone.

3. If the signal in the place is not good, the signal cannot be found, so you can search in another place. 4. Damaged mobile phone receiver: If there is still no signal despite the above reasons, and you suspect that the mobile phone receiver is broken, please go to the mobile phone after-sales location for testing and repair.

Hello kiss The above is the operation steps sorted out for you I hope mine is helpful to you, yo trace omen kiss <>

Is it solved? I'm also in a similar situation after leaving the province without a signal, can't play **, and can only use the 4G signal after turning off the 5G signal.

1. Network problems or network can't be covered. When the network coverage is not good, it is generally located in mountainous areas, basements, elevators and there is shielding or signal interference, there will be no signal or weak appearance. The process of network commissioning, optimization and maintenance may also cause panic, and generally the network will return to normal and the mobile phone signal will return to normal.

2. Problems with the phone itself. **Receiver can be an issue. Need a repair point to see.

Of course, KGI can rule out the cause of SIM card damage. Depending on your situation, it could be due to the following reasons:1, in your area, the network has been adjusted recently.

2. You may have a problem with the phone receiver, sometimes good and sometimes bad. The friend card to your mobile phone is normal, it may just be staring at the state of caution. To rule this out of the equation, you can look at the service points.

The reason why there is no signal on the mobile phone is because the signal will be affected or cancelled by various factors such as terrain, landform, and tall buildings during the propagation process, and if you are in a relatively closed place, the signal will be affected. Here's how to deal with it:

Turn the phone back on and off and try again;

Swap the SIM card to a family member's or friend's phone and try again;

Check to see if other Unicom users around you have a signal;

Check whether your late number has been activated for roaming outside the province, if not, it is recommended that you enable the roaming function outside the province before re-using.

If there is no signal, it is recommended that you contact the local Unicom customer service for feedback.
